London, ON, October 1, 2024 \u2013 <\/span><\/b>A new study has found that 29 per cent of people in Ontario who undergo endometrial ablation will have a subsequent hysterectomy to remove the entire uterus within 15 years.<\/span>\u00a0<\/span><\/p>\n

Researchers from <\/span>ICES, <\/span><\/b>the <\/span>Schulich School of Medicine & Dentistry at Western University, <\/span><\/b>and <\/span>Lawson Health Research Institute <\/span><\/b>examined <\/span>76,446<\/span> patients who were followed for 15 years, addressing the question of surgical interventions after a first endometrial ablation (EA).<\/span>\u00a0<\/span><\/p>\n

EA is a minimally invasive surgery that treats abnormal uterine bleeding (AUB) and is often offered as an alternative to hysterectomy. EA has been established as a safe procedure with low complication rates, but less is known about whether people undergoing EA will need further surgical intervention down the road.<\/span>\u00a0<\/span><\/p>\n

Published in the journal <\/span>Facts, Views & Vision in ObGyn, <\/span><\/i>the study included patients who had undergone their first EA in Ontario between 2002 and 2017.<\/span>\u00a0<\/span><\/p>\n

\u201cThese results provide valuable information to care providers, who can counsel their patients about more realistic outcomes of endometrial ablation, and the potential need for a future hysterectomy,\u201d says lead author Dr. Jacob McGee, an adjunct scientist at ICES Western, assistant professor in the department of obstetrics & gynaecology at Schulich Medicine & Dentistry, and associate scientist at Lawson.<\/span>\u00a0<\/span><\/p>\n

Risk of hysterectomy shows no signs of plateauing\u00a0<\/span><\/b>\u00a0<\/span><\/p>\n

The study found 22 <\/span>per cent<\/span> of patients received a subsequent surgical intervention after their primary EA.<\/span>\u00a0<\/span><\/p>\n

Within one year of EA, five<\/span> per cent<\/span> of women went on to have a hysterectomy. This increased to 17<\/span> per cent<\/span> at five years, 23<\/span> per cent<\/span> at 10 years and 29<\/span> per cent<\/span> at 15 years. This increase showed no evidence of plateauing by the 15-year follow-up.<\/span>\u00a0<\/span><\/p>\n

People who were younger, had a complex diagnosis, or previous abdominal surgery (such as tubal ligation) were more likely to have a subsequent hysterectomy.<\/span>\u00a0<\/span><\/p>\n

\u201cThe large number of women progressing to hysterectomy following a primary EA is concerning and suggests that EA is best considered as an intervention that will improve symptoms in the short-term and will ultimately delay the need for a hysterectomy, rather than prevent it,\u201d says McGee.<\/span>\u00a0<\/span><\/p>\n

Another finding showed a link between surgeon experience and future surgical risk following EA. As the experience of the surgeon increased (using their age as a surrogate measure), the likelihood of a person requiring a hysterectomy decreased by three<\/span> per cent<\/span> for each increase in year of experience.<\/span>\u00a0<\/span><\/p>\n

\u201cWe suggest that if endometrial ablation is to be performed that clinicians consider how they communicate longer-term outcomes to patients,\u201d says Dr. George Vilos, a professor in the department of obstetrics & gynaecology at Schulich Medicine & Dentistry.<\/span>\u00a0<\/span><\/p>\n

The researchers call attention to the potential use of combination treatments, including IUDs or hormone replacement therapies, which may extend the effectiveness of EA, and could eliminate the need for additional surgeries if patients were to enter menopause. They note that further research is needed to explore these options.<\/span>\u00a0<\/span><\/p>\n

The article \u201cHysterectomy rate following endometrial ablation in Ontario, a cohort analysis of 76446 patients\u201d was published in the journal Facts Views & Vision in ObGyn.<\/span><\/i>\u00a0<\/span><\/p>\n
